Electrostatic Filters

Electrostatic Filter

Roasting coffee is a beautiful process in which green coffee beans are being transformed into roasted beans that can be used to brew fresh, aromatic coffee. The roasting process always produces by-products like smoke and smell. For coffee roasters up to the W15A a electrostatic filter can be used to reduce the emission. The electric charge will filter fine dust and partials leaving your emission cleaner.

The exhaust during the coffee roasting process

During the roasting process the green beans are being heated with hot air leading to the first crack when the beans break out and are enriched with distinct flavours and complexity of the typical coffee aroma’s. However, the fresh green coffee beans also contain a certain variety of chemical compounds. During the roasting, when heat is applied to the coffee beans, by-products will set free leading to smoke and smell.

Electrostatic Filters reduce smoke.

Depending on the location of your company, it may be sensible to filter the exhaust. This is very convenient when your company is situated in a crowded area like a city centre or a residential area. Electrostatic filters remove fine particulate matter such as dust and smoke from the air stream using the force of an induced electrostatic charge. In this way the electrostatic filters can clean the air for -90% from smoke. It is easy to use electrostatic filters effectively for coffee roasters with a capacity below 25 kgs. This means you can combine them perfectly with the Giesen W1 Coffee Roaster, the Giesen W6 and the Giesen W15.

Afterburner

If your company uses the Giesen W30a Coffee Roaster the emission will be too high for an electrostatic filter to handle. In this situation it is highly recommended to install an afterburner. Especially because of the intensity of the roasting capacity, the nuisance will increase equally. With an afterburner the emitted air of the roasting process will be burned a second time. This ensures that the smoke and smell will be drastically reduced up to 90%. This is the best investment for your company to solve all exhaust problems that naturally belong to the roasting process.
